Idler Rolls Anodized Coatings and Rubber Coverings

Idler roller high release coatingsWINtrac Coatings

The recommended coating for WINertia precision idler rolls is WINtrac™ High Release Coatings. This revolutionary coating line is formulated for a wide range of applications including web roll handling, printing processes, and adhesive applications.

The WINtrac™ coating is directly integrated with the WINertia™ aluminum idler roller manufacturing process. By eliminating the outsourcing time normally associated with coating rollers, we provide customers with the highest quality coated rolls at the lowest possible price. This inline integration also allows for the same short lead-time for a WINtrac™ coated roll as for an uncoated roll – just 5 business days.
